How Can I Implement URL Rewriting in PHP Using .htaccess and a PHP-Based Approach?

URL Rewriting with PHP

URL rewriting transforms URLs into a more readable and user-friendly format. This guide explores two methods to achieve URL rewriting in PHP: mod_rewrite with .htaccess and a PHP-based approach.

.htaccess Route with mod_rewrite

To use mod_rewrite, create a .htaccess file in the root directory and include the following:

RewriteEngine on
RewriteRule ^/?Some-text-goes-here/([0-9]+)$ /picture.php?id=

This will redirect all URLs matching the regular expression to picture.php, passing the ID as a parameter.

PHP Route

To use PHP, modify the .htaccess file with:

FallbackResource /index.php

In index.php:

$path = ltrim($_SERVER['REQUEST_URI'], '/');
$elements = explode('/', $path);
if(empty($elements[0])) {
    ShowHomepage();
} else switch(array_shift($elements)) {
    case 'Some-text-goes-here':
        ShowPicture($elements);
        break;
    ...
    default:
        header('HTTP/1.1 404 Not Found');
        Show404Error();
}

This approach gives greater flexibility in handling complex URL structures.
